[SILParser] fix a few issues to enable parsing of sil from swift array.

1> a type mismatch for tuples with default argument kind not being none.
The fix is to compare unlabeled type.
2> a mismatch of size of conformances.
We used to collect all conformances of the generic param list. The fix is
to only collect conformances for the archetype we are working on.

Fix rdar://problem/17758203 and rdar://problem/17781140.
